This will be noisy as hell. Much better to just plop two 120mm fans on it with zip ties. Along with an adapter for the fan header on GPU. (just check that the header can provide enough power, which it usually can)
Oh okay, I was interested in Figma Editor seat. I'd suggest editing the original post, it seems to create that confusion. In common parlance, Figma Files are Figma Design files and Team Libraries are for Figma Design files to share common assets.
Its the default configuration on AP201, which confused me initially as well. Also with the 850x, I think its not possible to do a PSU fan on the outside setup without using an L-shaped adapter for the power cable (something to do with the orientation of the power point on the PSU)
I think 105 will be thermal throttling. I don't think hwinfo separately mentions thermal throttling. You should definitely try a repaste and see if that makes a difference. Cheaper than buying a new cooler.
Get just the case (the coolermaster one linked above seems good) then with a 3 cheap fans, 2 for front intake and one for top exhaust. The cooler seems to be an unnecessary expense. What temps are you seeing? Have you tried cleaning the cooler up and reapplying thermal paste? Like I said, the...
Get the Deepcool AG400 to cool your CPU but don't skimp on the case. Would recommend going for the case upgrade and getting a cooler once you upgrade the CPU (as in most cases, even the stock coolers would serve your purpose)
